Definitions

  • the invention relates to a mower blade for an oscillating, straight-line movement with a knife rail, which consists of at least two arranged one behind the other along a longitudinal axis Partial rails consists, which via connecting means with each other are connected.
  • Such mowing knives are preferred in harvester harvesters, for example, a combine harvester used.
  • a combine harvester used by virtue of the considerable mowing widths result mower blades with a Length of 9 meters and more, by a drive back and forth be moved, with the blades attached to the knife blade the crop in cooperation with Mähfingern, the Make counter cutting, cut off.
  • Subject to use the knife blades a more or less severe wear.
  • mower blade with the above lengths are quite flexible, since they usually from a relatively thin in cross-section rectangular profile, so that the transport from the manufacturer to the machine operator on the field only consuming to accomplish is. The cost of packaging and the Transport is therefore often higher than that for the mower blade itself.
  • Sectional knives have a length of about 3 meters, so that, for example, for a 9 meter long mower blade then in total three sections are merged and linked. Such lengths are still easy to pack and transport. It requires, however, that the three sections on two Connecting points are to be interconnected. Such joints are subject to high mechanical stresses, As a rule, at least 500 double strokes per minute are performed which leads to over a thousand load changes. In addition to the load from the acceleration and deceleration of the reciprocating masses must also be the cutting forces be transmitted.
  • US 4 805 390 describes a mowing knife with one of partial rails assembled knife rail, which in the connection area each reduced to half their strength are and overlap. In this state they are through Screws connected together. While at the aforementioned Embodiment normal round shaft bolts are used is proposed in US 4,854,114, instead of the usually round shaft bolts such with one in cross section oval shaft to choose in the direction of stress the mass forces due to the reciprocating motion a larger cross-section, which is subject to shear, to provide.
  • the invention has for its object to a mower blade create, whose knife rail composed of several sub-rails is, in which the connection area designed in such a way is that high forces resulting from the reciprocating motion the masses result, received by the connecting means can be. Furthermore, an improved Recording of the buckling forces done.
  • An advantage of this training is that both the knife blades participate better in a transfer of forces than also used an improved material for the connection tab which is capable of absorbing higher forces, both in terms of the stress from the reciprocating masses as well as in relation to it resulting buckling stress, so that overall the joint area can be kept so that he measures the dimensions the sub-rails in the area outside the recesses not exceeds.
  • the power transmission is particularly advantageous, even if a knife blade with a second through hole to a first through hole in the region of a recess and with a second through-hole in a longitudinal section outside the recess is aligned.
  • This is a Anchoring this knife blade in a region of the sub-rail, which has the full material thickness and in one Area where the connection tab is located. Consequently also produces this knife blade an improvement of Power transmission.
  • connection areas i.e. in particular the length of the recesses be designed differently along the longitudinal axis.
  • the connecting strap four third through holes and the abutting ones Partial rails in their recesses respectively have two first through holes.
  • An extended overlap area with the connecting tab is achieved by that the connecting tab has eight third through holes and the abutting sub-rails in their recesses each have four first through holes.
  • the connecting strap consists of a high-strength Steel, in particular of a spring steel, so in particular the buckling forces can be accommodated favorably and not lead to injury.
  • the connection ratios be made favorable by that the thickness of the connecting plate maximum of the difference from the first distance reduced by the second distance corresponds.
  • FIGS. 1 and 2 show only a limited length a mowing knife, in which the joint area of two Sub-rails 2, 3 is shown in detail.
  • the two partial rails 2, 3 are arranged one behind the other along the longitudinal axis 1.
  • the two sub-rails 2, 3 are in the area in which they are connected to each other, identically formed, so that just a description of the special design in this area takes place with respect to the first sub-rail 2.
  • the first Sub-rail 2 has a mounting surface 4, which is continuous just designed.
  • the second distance B is smaller designed as the first distance A.
  • the two sub-rails 2, 3 with the butt joint 10 abutting are arranged.
  • the second Sub-rail 3 one of the first sub-rail 2 corresponding recess.
  • the Design of the second sub-rail 3 is mirror symmetry to the first sub-rail 2 with respect to a plane of symmetry represented by the butt joint 10.
  • first through holes 11 are arranged.
  • knife blades 12 On the mounting surface 4 of Partial rails 2, 3 are knife blades 12, wherein these each two second Through holes 13 have arranged at a distance C from each other are.
  • Each knife blade 12 has a width E. They are contiguous arranged one behind the other along the longitudinal axis 1, one of the knife blades 12, namely the knife blade 12a, the butt joint 10 is arranged overlapping, so that one of its second through holes 13 with a first through hole 11 of the first sub-rail 2 and the other of the two second through-holes 13 with a corresponding first through hole 11 of the second Sub-rail 3 is aligned.
  • the to the knife blade 12 a adjacent knife blades 12 b with their second through holes 13th are arranged so that they with a first through hole 11, which is still is in the region of the recess 7 of the first sub-rail 2, agree, while the associated first through hole to the further second through hole the knife blade 12, lies in a longitudinal section in which the mounting surface 4 is arranged to the second surface 5 with the greater distance A, So thicker.
  • the knife blade 12b thus covers the butt joint 10 on the side facing away from the third surface.
  • 3 is a connecting plate 14 whose thickness D maximum the difference from the first distance A is reduced by the second distance B, so that it does not project beyond the second surface 5.
  • the butt joint 10 can be made of a high-strength material, for example Spring steel, to be made.
  • the Connecting tab 14 on the one hand by the Connecting tab 14 and on the other hand supported by the mowing blades 12a, 12b, wherein for connecting head screws 16 in conjunction with nuts 17 as a connecting means serve.
  • the Connecting means are used, anyway for the attachment of the knife blades 12 are required, while still the grid is respected by the Bore distance C of the second through holes 13 of the knife blades 12th is predetermined.
  • the two sub-rails 2, 3 only the abutting areas are shown. They are designed to be longer overall, as previously described, i. to have each about three meters in length, with two such sub-rails 2, 3 abut.
  • a sub-rail, for example, the sub-rail 2 can at one end with a Connecting head designed for connection with a knife drive. The Knives are then guided, for example, in Mähfingern, as in US 4,854 114 are shown.
  • connection region is designed so that the connecting plate 14 with three knife blades in operative connection stands.
  • connection area based on the two sub-rails 2, 3 has been explained, is applicable to versions with more or two sub-rails.
  • FIGS. 3 and 4 there is only a relationship to the embodiment according to Figures 1 and 2, a difference in that the Connection area is running longer.
  • the description related to Figures 1 and 2 also applies to the components of the embodiment according to the figures 3 and 4, wherein for the same components position numbers were selected, the those of the corresponding components of FIGS. 1 and 2 have a numerical value, which is increased by the numerical value of one hundred. Insofar as regards the description of these components to the description of the corresponding components referenced in connection with Figures 1 and 2. However, the following will be the Differences explained in more detail.
  • the recess 107 in the first and second sub-rail 102, 103 along the longitudinal axis 101 is made longer, so that a larger length section the first sub-rail 102 with an arrangement of the second surface 105 in proportion given to the mounting surface 104 with the reduced second distance B. It a total of four first through holes 111 are provided in this area, so that a total of five knife blades 112a, 112b are involved in the connection.
  • the connecting strap 114 is also designed to be longer.
  • rivets are in two places 18 shown.
  • the load is to a larger number of capscrews, i. Lanyards distributed as at the embodiment according to Figures 1 and 2.
